The equation of the normal to the cur...

The equation of the normal to the curve `y=x(2-x)` at the point `(2,\ 0)` is `x-2y=2` (b) `x-2y+2=0` (c) `2x+y=4` (d) `2x+y-4=0`

Text Solution

Verified by Experts

The given curve is ` y=2x−x^2 `
i.e, `x^2−2x+y=0`
Now the equation of the tangent at the point `(x_1​,y_1​)=(2,0)`
or, `x x_1​−(x+x_1​)+1/2​(y+y_1​)=0`
i.e `2x+(−1)(x+2)+1/2​(y+0)=0`
